Trying to set thermal stat to cool

Look at the bottom of the T'stat or in the newer ones click menu and follow instructions to preset individual days or on some week and weekend if there is a switch at the bottom set it on the cool selection click the menu button if it has a next buttton then click it until it gets to the degrees and push the <or> button until you get to the temp you want it to be at and then click next until you have all the days programed to the temp you want it to stay at and when your finished push the done button if it has one and it should be programed for the cool side to set the heat set it to heat and do the same as you did on the cool part remember down for cool and up for heat on the degrees you set them on example if you set it 78 for the temp on cool and during the day you want it cooler set it to lower temp say76. if you set it 79 then it won't come back on until the temp is 79. Maybe this will help some programable t'stat are a little more complicated then this

I have a Yamaha that I cant find out what model it is. I think its the xs 650 but im not for sure. All I know is that it was made 7/78 and the Serial number is 2Lo - 105468. It has twin cams, elc. starter...

It is a 1979 Yamaha XS400F. Although it was built in 78 it is a 79 model year with that serial number. 392cc plus the serial number both ties up with it being an XS400.

AC Thermostat is set to 78 but wont cool past 79 or 80

If your unit is running 24/7 you are either low on charge or the unit is to small for your house.
A 20° temperature difference is about normal for the room air vs the air coming out of the ducts, but the room air and the leaving air should keep getting colder and colder.
An air conditioner should cycle approximately 3 maybe 4 times in an hour if it's properly sized.
As for the thermostat thermometer they are very cheap and are more for reference than actual temperature, so if 78° is not comfortable, then you should set it lower but not rely on thermostat being accurate or what the thermometer is saying as long as it is consistent.
The air conditioner and thermostat can also be set below 78°, there's a lot of people set them at 72° and below with no problems.
the only thing is if you have real low humidity you'll need to watch indoor coil or the suction line (the big line) on your outdoor unit and make sure it doesn't freeze up on you.

Fan is blowing but air is not cool, outside pumps

If I understand you have two units one top and one bottom. If one is not running you have a problem. It will cause the other unit to work harder. Check breakers and the basic things. But you may need to call a service tech ask for free estimate. Russ

Need to know what the settings are for the range adjustment A,B,C,D slide switch on the front panel on a Amana PTH123A35AC PTAC

Here they are;

Position A, Cool 70-78, Heat 65-73
Position B, Cool 68-81, Heat 68-76
Position C, Cool 66-83, Heat 61-78
Position D, Cool 63-88, Heat 58-83

Amana calls this a Temerature Limiter and says to only set one switch on at a time. If all switches are off then the unit is at full operating range.
Please rate this answer to let me know if it was the fix.
